The non-rotating geometry keys the pins in place so they cannot spin or drift once installed, eliminating one of the most common headaches on a hard-use AR lower and keeping your trigger group stationary session after session.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eDesigned as a direct drop-in for any \u003cstrong\u003emil-spec\u003c\/strong\u003e AR-15 or M16 lower receiver using \u003cstrong\u003e.154\"\u003c\/strong\u003e hammer and trigger pins, this kit installs in minutes with basic hand tools and is an absolute must-have upgrade for duty rifles, competition builds, and hard-use platforms alike.\u003c\/span\u003e\u003c\/p\u003e","brand":"KNS Precision","offers":[{"title":"Default Title","offer_id":55335054967106,"sku":"NRTHPGENJJBK","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/alt_9c523dc0-70e9-4b94-8cf1-933e9ef08264.jpg?v=1785169621","url":"https:\/\/centerfiresystems.com\/products\/kns-precision-gen-jj-non-rotating-154-trigger-hammer-pin-kit-ar-15-m16-black","provider":"Centerfire Systems","version":"1.0","type":"link"}
